A beam of electrons is incident on a region containing a uniform electric field as shown below. The electrons in the beam each have a speed of 4.5 × 10° m/s. While in the electric field the electrons accelerate toward the top plate. Positively charged plate - Electron beam Negatively charged plate Note: You will want to make your measurements on this diagram. Based on your measurements, determine the strength of the uniform electric field strength in the region between the parallel plates

Two small plastic balls hang from threads of negligible mass. Each ball has a mass of 0.230 g and a charge of magnitude g. The balls are attracted to each other, and the threads attached to the balls make an angle of 20.0° with the vertical, as shown in the figure.(Figure 1) Part A Find the magnitude of the electric force acting on each ball.
